"[His] daughter, Linda Hope, would often peek down the grand staircase to see who was coming," Mills said. "She once spoke to Lucie Arnaz and Maria Cooper about doing a book about watching celebrities come and go called 'Seen From the Landing.'"

Bing Crosby, Hope's best friend, was a constant guest, as were presidents, including Richard Nixon, who reportedly once landed his helicopter on the sprawling grounds on his way to play golf.

Hope bought the land — once a walnut grove — in 1939 and began construction on his custom home. The house was renovated in the 1950s, and according to the LA Times, was constantly updated throughout the family's lifetime in the residence.

The living room of Bob Hope's Toluca Lake home was often filled with friends.

"The estate was always impressively staffed," explained Mills. "A full-time cook, butler, estate manager and two housekeepers manned the property on a daily basis, while additional staff was hired for large receptions."

Designed in an English traditional-style, the main home has 8 bedrooms and 8 bathrooms on a floor plan designed for entertaining. A massive foyer leads to a vast formal living room with walls of glass overlooking the grounds. The main floor also holds an office, family room, bar and billiard room, formal dining room as well as a family dining room and chef's kitchen.
